With the button trait VoiceOver will read “button” after the accessibility label and will indicate the user that, when focused, they can double tap anywhere on the screen to interact with it. UIButton has this trait by default.

The button accessibility trait in VoiceOver
9 Jun 2022
Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

Images that convey important information should have the .image accessibility trait and provide an alternative text in the accessibility label. "Image" will be added to VoiceOver's utterance and the user will be able to use Image Explorer. Image Explorer is fairly new, introduced just a couple years ago. But if you were appropriately configuring the image trait, users suddenly got this new functionality for free. Isn't that awesome? With VoiceOver on, open Image Explorer by swiping up in an image and double tapping. It lets users find people (with a basic description and positioning in the photo), objects or text in images, using on-device intelligence. It is very cool!
When using Voice Control, say: "Show names". You'll see all the accessibility labels for interactive elements overlaid on the screen. It will help you identify labels that can be improved, or actually missing. Labels are not just for VoiceOver.
When interacting with a button with VoiceOver, the accessibility label is repeated to the user. If you are playing some audio, it could be difficult to listen to it properly. To avoid that, you can add the .startsMediaSession accessibility trait.
